gametophyte. It is not clearly differentiated in the life cycle of the lower plants.

The asexual form, known as a sporophyte, is represented by the fern plant as it is commonly known.
A pine tree is called a sporophyte because it develops from a spore produces spores is haploid can reproduce sexually and asexually cannot undergo meiosis
Ulva produces isomorphic thalli for its diploid sporophyte and haploid gametophyte.
Sometimes she could remember, sometimes there were flashes of brilliance, but sometimes she was lucky to remember the difference between the gametophyte and sporophyte stages of a fern.
The independent origin of this conducting system is of great interest for comparison with the vascular system of the sporophyte of the higher plants.
The last-mentioned case has been regarded as representing an apogamous development of the sporophyte from the gametophyte comparable to the cases of apogamy described in Ferns.
The common maiden-hair fern (_Adiantum pedatum_) has been selected here for studying the structure of the full-grown sporophyte, but almost any other common fern will answer.
The terms oöphyte (egg-bearing plant) and sporophyte (spore-bearing plant, or sporogonium) are sometimes used to distinguish between the sexual plant and the spore-bearing one produced from it.
The classification is at present based largely upon the characters of the sporophyte, the sexual plants being still very imperfectly known in many forms.
When condition is favourable the seed germinates to a new young sporophyte - a pinetree seedling.www. milkandhoneyfarm.com Sarah Lea explains how to use the Nutrimill to turn wheat berries into whole wheat flour.
